Hi silasmoeckel, thanks for your reply.
I'd like to control the lightbulb, to switch on, off, but also to dim the light (have the intermediate states).
I guess I should have said I want to do a remote controlled Dimmer.
I need to be able to control it from distance and through walls, the same way you use wifi in an apartment, so I guess bluetooth is not good.
I was thinking of RC to keep the costs low and also the size of the receiver. What do you think?
There will be many receivers with ideally an unique id, so I need to think of an elegant way to set it all up.
As for dimming the light, i thought there are some kind of transistor I could use but apparently that's not right.
Anything else that is very limited in size but that does the job?
Thanks
Riccardo
